0f0f3bd1e0 lavfi: use av_default_item_name() as filter private context logger
avfilter_default_filter_name() is supposed to access an AVFilterContext

name of the instance filter if defined, otherwise the name of the filter.

This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.

06bf6d3bc0 vf_overlay: rewrite request/push logic.
The old implementation, upon receiving a frame on the main
input, would request an overlay frame if necessary. This could
generate an infinite recursion, off-by-one frame mismatch and
other harmful effects, especially it the split filter is present
upgraph.

The new implementation uses the linear approach: it uses two
buffer queues for frames received out of turn and forwards
request_frame calls to the input where a frame is necessary.
